A maximum operating ambient temperature of 35 °C is assumed at a maximum altitude of 1000 m
and 2 kHz switching frequency. Derating is required for higher switching frequencies, ambient
temperatures and altitudes.
Table 4-3 Incoming supply cable sizes and connections
Motor cable sizes
The nominal output cable sizes assume that the motor maximum current matches that of the drive.
Where a motor of reduced rating is used the cable rating may be chosen to match that of the motor.
To ensure that the motor and cable are protected against over-load, the drive must be programmed
with the correct motor rated current.
The number of cables is always 1 or 2 per installed power module
